DETAILED DESCRIPTION OF THE INVENTION

The present disclosure provides a shoe sole that allows for rotation via discs built into the soles of at least one shoe in a pair of shoes. Rotating discs are provided in the soles which may be advantageous for a wearer when participating in a sport or walking. In at least one embodiment, the presently disclosed shoe sole may counteract the lack of sole rotation, or resistance to rotation, at a particular instance or ground contact orientation. For example, at a point in a golf swing.

A main feature of the present disclosure may be the spin function of the discs built into the sole of the shoe. The discs may spin 0-360 degrees about their center and the sole of the shoe. The sole of the shoe may be built with 2 or more discs and up to as many as 25, or more. The discs may be of varying sizes or may be the same size. For example, a plurality of little spinning discs may be incorporated in the sole of a shoe. The discs can be free flowing or made with a tension tighten mechanism to allow the person to adjust the spin rate or ease of spinning.

The number of discs, size of discs, and placement of discs may be tailored to provide a desired degree of rotation, or resistance to rotation, at a desired time. For example, when a golfer swings a golf club it may be desired to provide a lesser resistance of the foot on the ground at the end of the swing, or after the golf ball has been hit with the golf club. In at least one embodiment of the present disclosure, a shoe sole comprises a hind foot or heel portion, a midfoot or arch portion, and a forefoot or toe portion. At least two rotatable discs are in the toe portion, wherein each of the rotatable discs is configured and disposed to independently rotate 360° about the shoe sole. This embodiment may provide a desired lessening of resistance to rotation at a desired time. For example, upon hitting a golf ball, a golfer may have a sole contacting a forefoot or toe portion with the ground and it may be desirous for that shoe to rotate with lesser resistance as compared to a sole not having the rotating discs. This may relieve a rotational force on the wearer's knee or ankle.

One or both shoes, in a pair of shoes, may have rotatable discs. Rotatable discs may be positioned and sized to provide desired degree of rotation. Rotatable discs may be removable or configured to be positioned, or repositioned, at desired locations.

In at least one embodiment of the present disclosure, a spin disc mechanism provides for rotation of the discs from 0-360 degrees, counterclockwise or clockwise. The shoe sole of the present disclosure may help reduce knee twisting damage for athletes and non athlete persons using the presently disclosed spin technology sole in the shoes.

The rotating disc in the soles may be built with all kinds of different materials like metal, plastic PU, EVA foam, petroleum rubber, synthetics, rubber, foam, or other materials. The rotatable disc may be configured to be attached to a sole with some hard mechanism to withstand the twisting and rotation of the disc, as there may be a lot of torque in the twisting of the sole disc mechanism.
